I have noticed sales on PC3200 memory but never PC2700. Can I use PC3200? I currently have 1 256mb and 1 128mb PC2700's . My plan was to replace the 128mb with a 512mb. Can I use PC3200? Can I use a 512mb PC3200 with a 256mb PC2700?
Also, in using some of the memory searches by various vendors they show different part numbers for Dell compatibility. Does it really matter?
